Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, it should be noted that in adding reference numerals to the components of each drawing, the same components are given the same reference numerals as much as possible even though they are indicated on different drawings. In addition, in describing the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, preferred embodiments of the present invention will be described below, but the technical spirit of the present invention is not limited thereto and may be variously implemented by those skilled in the art without being limited thereto.

The present invention is characterized in that it provides a database of song information in all currently receivable frequency bands to the driver using a two-channel radio tuner and modem.

In the existing radio broadcasting, it was impossible to know information about music being broadcast in a state where broadcasting was not received through frequency change. An object of the present invention is to help a user receive a desired broadcast by providing the user with information about music being broadcast on a frequency channel other than the frequency currently being received.

It will be described in more detail below with reference to the drawings.

1 is a conceptual diagram illustrating an internal configuration of an AVN (Audio Video Navigation) system according to an embodiment of the present invention.

Referring to FIG. 1 , an AVN system 100 includes a digital signal processor (DSP) 150 , a modem 140 , a controller 130 , a memory unit 120 , and a display unit 110 .

The DSP 150 receives and processes the RF signal from the antenna 161 .

The DSP 150 includes one antenna 161 and two tuners 151 and 152 . The branch circuit 160 is provided at the input terminal of the antenna 161 , so that the RF signal input to the antenna 161 is branched and input to the tuner 1 151 and the tuner 2 152 .

The tuner 1 151 is used to receive a frequency of a radio channel that the driver currently wants to listen to. That is, it serves to receive a radio broadcast currently being listened to by the driver.

The tuner 2 152 serves to receive and search for a receivable channel frequency in the background. Separately from the tuner 1 ( 151 ), each frequency is received for a predetermined time and serves to transmit the received voice signal to the controller ( 130 ).

For example, the currently receivable frequencies are 87.1 MHz, 87.9 MHz, 90.1 MHz, … , 107.9 MHz, the controller 130 analyzes the currently broadcast music information by receiving at regular intervals from 87.1 MHz to 87.9 MHz and 107.9 MHz. However, if there are a large number of receivable frequencies, the update information may be inconsistent because the song is changed for one cycle or time, so it is preferable to reduce the update time by selectively receiving only the desired frequency by the user.

The modem 140 performs a function of accessing the web to receive song information.

The memory unit 120 stores the user's favorite music.

The control unit 130 includes a comparator 131 that compares and determines the music information.

The control unit 130 analyzes the voice digital signal received from the DSP 150 and transmits it to the modem 140 . The modem 140 searches the web server using the received information and transmits song information and singer information to the controller 130 again. As shown in FIG. 2 , the controller 130 converts the song information for each frequency into a database and transmits it to the display device 110 so that it can be shown to the user.

2 is a reference diagram for explaining a method for analyzing music information in an AVN system according to the present invention. In this embodiment, the control unit 130 includes information 210 on a broadcast channel through which the corresponding music is output as music information, a song title 220, a singer name 230, whether the driver's preference corresponds to 240, and the like. It can be made into a database.

As shown in FIG. 2 , the user can receive by selecting a desired frequency from among the databased information. At this time, when a desired song is selected by the user by adding a user preference function, the control unit 130 separately lists and stores the list in the memory unit 120 as shown in FIG. 3 , and lists the listed songs. During user selection, when the song is played on another broadcast, the frequency can be changed automatically. The controller 130 may simultaneously select several songs according to a user's input.

3 is a reference diagram for explaining a method of storing a favorite song in the AVN system according to the present invention. The controller 130 may generate a user favorite list including a song title 310 , a singer name 320 , a user preference 330 , and the like, and store it in the memory unit 120 . When a song checked in the user preference 330 is reproduced in another broadcast, automatic frequency change may be enabled.

Meanwhile, the AVN system according to the present invention may be implemented as an audio system having only an audio function.

Next, a method for analyzing music information of the AVN system 100 will be described.

The radio broadcast is input to the DSP 150 tuner as an analog signal through the antenna 161 . DSP 150 has two tuners.

The tuner 1 (151) transmits the frequency signal selected by the user as an analog or digital signal to the amplifier or speaker so that the user can hear it.

The tuner 2 152 searches for other frequencies in a predetermined pattern, receives them, digitizes the analog signals, and transmits them to the controller 130 in SPDIF or I2S format.

The control unit 130 extracts a portion of the digital signal received from the DSP 150 and transmits it to the modem 140 , and the modem 140 uses the natural frequency of the received music under the control of the control unit 130 and The same music can be extracted through a web search.

Next, a method for storing a favorite song and a channel change process of the AVN system 100 will be described.

The music information scanned by the tuner 2 152 is periodically recorded and updated in the memory 1 121 in the form of one record with the corresponding frequency, song name, singer, etc. as fields. Among the music information recorded here, music information selected as a favorite function is copied to the memory 2 122 , excluding the frequency, on the user's favorite list.

A song selected by the user from among the music information stored in the memory 2 122 is read by the comparator 131 whenever the music information in the memory 1 121 is updated.

The comparator 131 compares data read from memory 2 122 with data updated from memory 1 121 to determine whether they match. If there is matching information, the comparator 131 transfers the frequency information from the memory 1 121 to the corresponding record to the control unit 130, and the control unit 130 selects the channel of the tuner 1 151 according to the user's selection. make it change

4 is a flowchart illustrating a method of operating an AVN system according to the present invention. The following description refers to FIGS. 1 and 4 .

The operation process of the AVN system 100 has two types of operation, such as a tuner 1 151 and a tuner 2 152 as shown in FIG. 4 .

The tuner 1 151 is operated from the moment it enters the radio mode and always receives the frequency broadcast selected by the user.

Separately from the tuner 1 151 , the tuner 2 152 includes a process of operating in the background and a process of some user setting operation during broadcast reception by the tuner 1 151 .

In channel scan, it is possible to select a frequency to scan according to the user's selection. When a frequency is selected by the user, the tuner 2 152 periodically performs a channel scan in the background ( 421 ). Then, the tuner 2 152 transmits the information received through the scan to the controller 130 .

The controller 130 acquires music information in the form of a song name and singer from a web server based on information received from the tuner 2 152 through the modem 140 . The song information DB part 422 is a process in which the controller 130 stores the acquired music information in the form of a record having a song name and a singer as fields in the memory 1 121 . The data stored in the memory 1 121 periodically updates music information transmitted from the modem 140 .

In the Favorite List part 423 , the music information selected by the user from the memory 1 121 is retrieved and stored in the memory 2 122 . A song selected by the user from among the songs stored in the memory 2 122 is compared with the music information updated in the memory 1 121 ( 424 ).

If there is information that is matched by comparison, the frequency information included in the record is read from the memory 1 121 and the tuner 1 411 informs the user so that the frequency change can be made. Whether to change the frequency is determined according to the user's selection. When the frequency is changed (411), the tuner 1 (151) receives the corresponding broadcast and outputs it from the AVN system (100) (412).

The process of tuner 2 152 described above is continuously repeated.

5 and 6 are exemplary views for explaining an operation example of the AVN system according to the present invention.

It is assumed that a user is listening to a 98.1 MHz broadcast and has selected 87.1 MHz, 90.1 MHz, 107.1 MHz, etc. as a frequency channel to receive music information. You can select to view other channel information while receiving 98.1MHz broadcast, and when selected, it is as follows.

Music information currently broadcast on the frequency channel selected by the user can be viewed, and the corresponding broadcast can be received through channel selections 510 , 520 , and 530 as shown in FIG. 5 . In addition, music currently broadcast at 97.7 MHz can be separately stored in the Favorite List through the Favorite selection 540 .

6 is a Favorite List screen.

You can select a song you want from the Favorite List. If the second song is selected (640), when music having the same information as the second information among frequencies being scanned is received by the tuner 2 (152), a pop-up notification is displayed to the user, and the channel is changed according to whether the user selects or not This is possible.

7 is a reference diagram for explaining the structure of music information according to the present invention.

Music information is largely composed of header information 710 and data information 720 , 730 , and 740 . The data information 720 , 730 , and 740 are parts having actual music information, and the header information 710 includes some information of the data information 720 , 730 , 740 to efficiently compare the music information. part

The data information 720 , 730 , and 740 includes data 1 720 , data 2 730 , and data 3 740 , and information about a singer's name, song name, and frequency is stored, respectively.

For example, if the singer of music broadcast at 107.9 MHz is Artist and the song name is Title, it is stored in the memory unit 120 as shown in FIG. 7 . Here, the header information 710 has each of the first letters of Artist and Title. Therefore, when comparing the user's Favorite information with the music information being scanned in the background, only the header information of each is read and compared.

Since the header information 710 has a smaller amount of information than the data information 720 , 730 , and 740 , comparison/determination is possible quickly.

When the header information 710 does not match, the next information is compared without checking the data information 720, 730, and 740, and when the header information matches, additionally data 1 720 and data 2 730 ), the singer name information and the song name information are compared. After that, when the information matches, the frequency information stored in data 3 740 is read and a pop-up is displayed to the user to determine whether to change the frequency.
